As an accessory of the mobile phone, the charger is used to charge the mobile phone when the mobile phone is out of power. Unlike mobile phones, we often hold them in our hands. As for the charger, we often throw it away after charging it, and only remember it when we charge it again. Any electrical product has a service life, and if you don't pay attention to maintenance, it is easy to fail. When the mobile phone charger is not in use, it should be placed in a place where it is waterproof and moisture-proof, cold-proof, heat-proof, and strong chemical-proof products. Let's learn about the maintenance of mobile phone chargers.
How to maintain the mobile phone charger
1. Discharge static electricity when cleaning. Regularly clean the charger and charging port. When cleaning, use a damp cloth, or an antistatic cloth. Never use a dry cloth (static charge)!
2. Waterproof and moisture-proof. As an electronic product, accidental water ingress or exposure to humid air when not in use for a long time will cause different degrees of corrosion or oxidation to its internal electronic components.
3. Anti-drop and shock-proof. The mobile phone charger is actually a fragile part, and the internal components cannot withstand being beaten. Especially to prevent accidental landing during use. Do not drop, knock or shock the charger. Rough handling of the charger can destroy the internal circuit boards.
4. Anti-cold and heat-proof. Do not place the charger where the temperature is too high. High temperatures can shorten the life of electronics, damage chargers, and deform or melt some plastic parts. Also, do not store the charger in a place that is too cold. When the charger works in a supercooled environment, when the internal temperature rises, moisture will form in the charger and destroy the circuit board.
5, anti-strong chemicals. Do not clean the charger with harsh chemicals, cleaning agents, or strong detergents. To remove stains on the appearance of the charger, use cotton dipped in a small amount of anhydrous alcohol to scrub.
Use and maintenance of mobile phone chargers
There are two main types of mobile phone chargers on the market: the Android version and the Apple version. The two chargers are mainly different in the charging head. Of course, old mobile phones and old phones also have a variety of charging heads, but most of the charging heads for smart phones are similar and can be used universally.
Mobile phone chargers, in normal use, are also easily damaged if you are not careful. According to the internal structure of the charger, it is mainly the internal switching power supply that is easily damaged. The mobile phone charging port is made according to the principle of switching power supply. The AC 220V is converted into DC power for charging the mobile phone through voltage transformation, rectification and voltage regulation. Its series of work can only be completed through the work of various electronic original devices. For the specific circuit and working principle, you can find relevant books to read, so I won't say much here.
The common faults of chargers are as follows:
The internal circuit is burned out due to abnormal external voltage or poor contact with the external power supply. In this case only a new charger can be replaced.
The light is on, but it won't charge. There may be two reasons: First, the internal low-voltage circuit of the charger is damaged and no output; second, the charging cable is damaged, so that the voltage cannot be transmitted to the charging head and the charging cannot be completed. You can use a multimeter to measure whether there is a voltage output to draw a conclusion or replace a new charging cable to try.
When charging, the contact is not good, sometimes no. It can be plugged and unplugged several times during charging to make it in good contact. If necessary, the suspected part can be replaced and confirmed.
When the charger is not in use, it should be placed well, and don't be thrown away, otherwise it will not be found when it is used, and it must be unplugged from the power supply when it is not in use. Although the price of the charger is not high, it is also convenient to buy. But if you take good care of it and use it correctly, it is also necessary.
